Two endemic plant species extinct in India
The flora and fauna in the Indian subcontinent have started suffering from the climate change. India is one of the 12 countries in the world with most biodiversity. It is discovered that two plant species Cythodium Barodie and Isoetes Barodensis, which were named after city’s old name Baroda are about to go extinct.
A sub species of the bryophytes, Cythodium Barodie were first discovered in 1934. These plants could be easily spotted on the old buildings and walls. The non-vascular plant used to grow in old city areas like Pavagadh hilltop in Panchmahal district and Faculty of Science in MS University. But today spotting this plant has become a rare event. The Hansraj or ferns is the common name for the Isoetes Barodensis. The sub-species of the Pteridophytes undergo reproduction through spore and disperse as they are vascular in nature. In 1992, the species was declared to be extinct and was spotted in waterlogged agricultural land around the Harni Pond region last time.
Arun Arya, the researcher and professor who observed both of these species in the city has informed that change in the habitat and the climate change are major reasons behind the extinction of these plants. These species are the discovery of Dr A R Chavan, head of the Botany department in the MS University, Vadodara from 1962 to 1967. These plants were endemic in their nature and exclusive to particular region due to availability of appropriate atmospheric conditions and minerals.
Bryophytes are unique and important as they are the first form of vegetations on the land and useful in studying effect of the global warming on flora and fauna.
